The new Virtual Mission concept will provide NASA's Science Program with a powerful new, 'go-as-you-pay,' flexible, and resilient way of accomplishing its science observing program. The...

Space-Based Assembly Sequence Formulation for Evaluation of Large Orbital Assemblies
The challenges associated with constructing interplanetary spacecraft and space platforms in low earth orbit are such that it is imperative that comprehensive, preliminary process planning...

Design of a Support and Foundation for a Large Lunar Optical Telescope
NASA is considering a large lunar telescope [LLT] and a smaller diameter precursor telescope experiment on the Moon. The preliminary design of the 16-meter optical aperture is being performed...

Roof Management Alternatives for Aging Launch Infrastructure
This paper describes a Roof Management System approach to better cope with aging and deteriorating infrastructure support facilities at our national spaceports. It describes facility conditions...

Rocket Fuel to Earth Orbits from Near-Earth Asteroids and Comets
The analysis describes an architecture to bring 10,000 tons units of rocket fuel ore, propellant and construction mass back to low Earth orbit from newly discovered near-Earth comets or...

The New Munich Airport?Planning, Construction and Opening of a New International Turnstile Airport in Europe
The new Munich airport that began operations just recently dates back to the mid-1950. The paper discusses the general expansion plan which includes site selection; runway system planning;...

Soft Touch People Mover Central Control
The people mover central control systems perform many automatic functions, are built with off-the-shelf redundant hardware, include advanced color graphics and touch screen operator interfaces,...

Airport Landside Management: An Unique Airport Specialty
Air transportation has become a common and preferred method of travel, resulting in an ever increasing number of air passengers. The significant growth has resulted in unique and never...

Estimation of Pass-By Trips Using a License Plate Survey
The objective of the study was to determine whether it is possible to estimate the percentage of pass-by trips using a license plate survey instead of the traditional interview survey....

Lagrangian Transport Simulation Using Video Images to Store and Retrieve Parameters
A new technique based on Video Images for Storing and Retrieving parameters (VISR) and its application to model pollutant transport using the Lagrangian discrete parcel method is presented....

An Experimental Model Using a Graphical User Interface
This paper describes a program named Plume which runs on a microcomputer. The intended function of the program is to enhance an investigator's understanding of the estuarine environment...

Techniques for Visualization of Estuarine and Coastal Flow Fields
A variety of formats for the display of velocity vector components are presented and assessed. The effective transmittal of information to the viewer is the criterion emphasized. The special...
